CHAIN.

SPECIFICATION forming part of Letters Patent No. 274,752, dated March 27,1883.

' `application filed March 2o, 1882. (Model.)

adjacent thereto, made in the same plane withl the hook, and are adapted to be permanently coupled to similar links to form the complete chain; and the objects of my improvements are to so form a cast chain that it can readily be put together and the linksclosed with as little bending as possible, and to so form the chain that it shall be very strongand durable. I attain these objects by the mechanism illustrated in the accolnpanying drawings, in which- Figure 1 is a plan View of said chain as it Fig.

verse section of another, as on line x a: of Fig. 4.-. Fig. 3 is all edge view of one link; and Fig. 4 is an elevation of two links, which, with Fig. 2, is designed to illustrate thermanner of putting the links,together.

`'Ihe particular form of chain shown in the drawings is designed for a trap-chain; but I intend to apply the chain to other uses-as, for instance, halter-chains-in which case the links lnay be made alittle sllorter and heavier, and ot' course supplied with different trimmings. The links are oblong and their ends rounded, as shown. Upon one side ofthe link, near the roundedend, I form a slightopening the width of which is less than the diameter ofthe respective sides or body of the links, so that said body cannot pass through said opening. Near the opening in thelink I form a cross-bar, ct, for the purpose of strengthening the link and connecting the two sides of its body b. That end of the link which is upon one side of the cross-bar is substantially a hook, and the cross-bar lies in the same plane with said hook. This cross-bar I make thin enough to pass through the opening in the link, and consequently it is thinner than the body of the link b. The ends of the link-body at the opening are slightly beveled, so that when two of these openings are placed opposite each other, with one link at about right angles to the other, they may be Vhooked to-` link which have been closed. The body ot' the link at the end which projects but little from the cross-bar is so short as to require no strengthening except such as may be effected .by making this portion of the linktheavier than the rest, or, in other words, making the body ofthe link at this end of greater dialneter than the rest. It should be noticed that the hook or open end of the link lies in the same plane with the rest and constitutes a part of the whole link. The thin cross-bar is not in the nature of an end for a lilik; but the links are completely hooked together lirst, after wllich one link is slipped over the crossbar to bring the links into the desired position, and when the opening is closed the cross-bar prevents the links from heilig changed, end for end, ill the chain; V

The eye c of the ring A is cast open, like the links, and is slipped upon the first ylink in the manner before described, and represented ill Figs. 2 and 3, for two links. The wedge B may also be put on in the same way. The ring A is the end from which to workin forming a chain of these links. When the desired length of chain is formed the swivel d is secured to the last link. The swivel-eye is made solid,:9o

IOO

I claim as my inventionv 1. The link for chains, having a hook at one end, with a narrow opening, and a cross-bar or diaphragm adjacent thereto, made thinner than the side bar and in the same plane with the hook, and adapted to be permanently coupled to similar links to forma chain, in the manner described, and for. the purpose specified.

2. The link for chains, having a'body which, beginning at the side of the link near one end,

l extends along one side,`across one end, along the opposite side, and around the opposite end, to near the starting-point, Where a narrow open,1 ing is left, thereby forming one end of the link into a hook, and having also a cross-bar near 15 said opening,in the same plane With said hook, and forming the opposite end or part of the link into a closed or uncut eye, the complete link being adapted to be coupled to like links to form a chain by permanently securing the hook of one link within the uncut eye of the next adjoining link, substantially in the inanner described, and for the purpose set forth.
